Forests create the air we need to breathe. They provide shade and homes for people and animals. They give us wood for fuel and for building materials. And they are beautiful spaces! But deforestation means humans are destroying more forests every day.As towns and cities grow, people take more land from forests. Trees are cleared for space faster than we can replant them. Check out what happens when forests disappear—and if we can reverse what has already been lost.

Fossil fuels heat our homes. They power cars, trucks, and planes. But every use of these fuels adds to rising temperatures on Earth. And they are nonrenewable. Someday, they will run out.Since the 1800s, people have studied the effects of burning fossil fuels. This process puts gases in the air that contribute to climate change. Examine how fossil fuels have been used and the effect they have on our planet''s climate.

Earth is nearly 70 percent water. Most of this water is frozen in the form of glaciers. As our planet warms, glaciers are melting faster than usual. Sea levels rise, and water washes over coastal areas. Homes are destroyed. Habitats are lost.Scientists have been following the changes in glacier ice and ocean levels. Discover what they''ve learned and what changes humans need to make to keep our heads above water.

Los bosques producen el aire que necesitamos para respirar. Proporcionan sombra y hogar a personas y animales. Nos dan madera para combustible y como material para la construcción. ¡Y son lugares bellos! Pero la deforestación implica que los seres humanos están destruyendo más bosques cada día.A medida que los pueblos y ciudades crecen, las personas ocupan más tierra de los bosques. Los árboles se talan para obtener espacio con mayor rapidez que la que lleva volver a plantarlos. Averigua lo que sucede cuando los bosques desaparecen... y si podemos revertir lo que ya se ha perdido.Forests create the air we need to breathe. They provide shade and homes for people and animals.

Los combustibles fósiles calefaccionan nuestros hogares. Impulsan a automóviles, camiones y aviones. Pero cada vez que se usan estos combustibles, aumentan las temperaturas de la Tierra. Además, no son renovables, es decir que algún día se agotarán.Desde el siglo XIX, las personas han estudiado los efectos de quemar combustibles fósiles. En este proceso se liberan gases en el aire que contribuyen al cambio climático. Analiza cómo se han usado los combustibles fósiles y el efecto que tienen en el clima de nuestro planeta.Fossil fuels heat our homes. They power cars, trucks, and planes.

La Tierra está compuesta en casi un 70 % por agua. La mayor parte de esta agua está congelada en forma de glaciares. A medida que nuestro planeta se calienta, los glaciares se están derritiendo con mayor rapidez que la usual. El nivel del mar sube y el agua ocupa las zonas costeras. Las casas quedan destruidas. Se pierden los hábitats.Los científicos han estado siguiendo los cambios en el hielo de los glaciares y el nivel del mar. Descubre lo que hemos aprendido y qué cambios tienen que hacer los seres humanos para que no nos tape el agua.Earth is nearly 70 percent water. Most of this water is frozen in the form of glaciers.
